Mars is certainly a place which stretches our sense of scale in
geology. Volcanic features there are sometimes three orders of
magnitude larger than comparable features on earth, and there
are some features, such as the "paterae", which have never
been found on earth.

There are also the rampart, pedestal, and "splosh" craters, which
are generated by the unique conditions of Martian soil and
erosion effects. There's no question that such things make it
very hard to anticipate the appearance of certain features, or to
derive their causes based on terrestrial geology.

FYI, Viking frame 627A28 shows a volcano with an extremely
elongated summit vent, which is almost exactly the sort of
feature I have begun to suspect the Face began as.
